Comment 2 for bug 1031378

libusc is the shader compiler library. The crash is happening in that library and therefore this is almost certainly a driver issue. I am going to mark this as invalid for glmark2. Feel free to reopen if you have additional information suggesting otherwise.

As a workaround, you may to create your own benchmark list, excluding the benchmark that causes this error (it seems to be "terrain"). Note that in trunk (and the upcoming 2012.08 release) you have the ability to save/load benchmark lists from the GUI. You can find the default benchmarks here: https://bazaar.launchpad.net/~glmark2-dev/glmark2/trunk/view/head:/src/default-benchmarks.h
